Give them a try. I've had standard chocks for the last 10 years and just switched to the x chocks this year when I bought my new rig. The worse that can happen is that your not satisfied and return them for the x chocks. I have been pleased with them so far. They do stabilize the camper a lot better than I thought they would.

You can save yourself a lot vs Bal X-Chocks by doing a homemade version of the camco product. I made mine with pressure treated 4x4s and stainless steel threaded rod. Sorry I don't have pictures but others on the forum have also made them.

I used the Camco on my Surveyor for 5 years. They worked very well. the only thing I would say is to tighten them a bit more after your tires cool, but I believe you have to do that with most chocks of this type.

I have used the camco chocks when using a friends trailer before buying our own. Although they did their job, I did not care for them and would recommend something better.

I chose the RotoChock for us and other than the cost, I can't possibly imagine how they could be improved upon. It was a tough choice between the Roto's and the x-chocks...I probably would have been happy with the x-chocks too.
